JAR-WRENCH.

Specification of Letters Patent.

Patented Oct. 10, 1911.

Application filed June 3, 1911. Serial No. 631,066.

To all whom it may concern:

Be it known that I, HATTIE D. HINDs, a citizen of the United States,residing at Rutland, in the county of Rutland and State of Vermont, haveinvented certain new and useful improvements in Jar-Wrenches, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to ar wrenches and has for its objectto provide avery simple, etlicient and inexpensive device of this character whichmay be easily and quickly applied to the cover of a jar whereby the samemay be expeditiously removed.

A further object of the invention is to provide a wrench of the abovedescribed .character which is applicable to threaded j ar covers .orcovers of thatcharacter which have frictional engagement with theperiphery of the jar.

`With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view of myimproved wrench showing the same applied to a j ar cap or cover; Fig. 2is an enlarged side elevation showing the device applied to a can top;and Fig. 3 is a detail section taken on the line 3 3 of Fig. 2.

Referring in detail to the drawing and more particularly to Fig. 1thereof J designates a jar such as is commonly used in preserving fruit,and C the cover thereof which has threaded engagement upon the upper endof the glass jar.

My improved wrench embodies two primary elements, viz., a jaw member 5and the handle 6. Each of these members is formed from a thin plate ofsteel and the jaw member 5 at one end is disposed at right angles asindicated at 7 and formed with the circular enlargement 8 upon one faceof which the similarly enlarged end 9 of the handle 6 is engaged. Apivot pin or stud 10 is disposed through the end portions 8 and 9 of themembers 5 and 6 and pivotally connects the same. The other end of thejaw member 5 is curved as indicated at 11 and is formed into a reverselydisposed gripping point 12.

The point 12 of the jaw member 5 coacts with a gripping point 13 whichis formed upon the pivoted end of the handle 6 and extends therefrom inthe longitudinal plane of the bar or plate from which said handle isformed. The gripping point 13 is opposed to the point 12 of the jawmember 5 and is adapted to engage the annular wall of the jar cover at apoint diametrically opposite to that engaged by the gripping point 12.

When the body of the aw member 5 and the handle bar 6 are disposed inparallel planes, the upper edge 14- of the point 13 is disposed in aplane slightly above the point 12. This is of material importance in theremoval of can tops or other container covers having frictionalengagement with the walls of the container, as will be fully disclosedin the following description.

In the use of the device for the removal of the ordinary threaded jarcover as shown in Fig. 1, the gripping point 12 is first engaged withthe annular wall of the cover, said cover being received betweenopposite ends of the jaw member 5, the body portion of said memberextending over the top of the cover and in spaced relation thereto. Thegripliiing point 13 of the handle 6 is then forced into grippingengagement with the cover at a point opposite the engagement of thepoint 12 therewith, and said handle is forced downwardly so as to causethe curved edge 15 to bear with considerable pressure unon the cover. Acircular movement is now imparted to the handle whereby the cover isthreaded from the upper end of the jar and removed.

1n the use of the device for the removal of can tops, the point 12 ofthe j aw member 5 is engaged beneath the lower edge of the can top andthe handle 6 is disposed at an angle with relation to said jaw member asshown in dotted lines in Fig. 2 so as to position the point 13 beneaththe edge of the can top on the opposite side thereof. By pressingdownward upon the handle it will be obvious that the can top will beraised and disengaged from the annular wall of the can. By disposing thepoint 13 of the handle in a diii'erent plane from the point 12 of the awmember, suflicient leverage is obtained to remove the can top with asingle downward movement of the handle, and undue pressure of the bodyof the jaw member 5 upon the top is obviated. As the handle is forceddownwardly, the curved edge 15 of the point 13 forces the upper edge ofthe Wall of the container inwardly, thereby releasing the air frombeneath the can top and greatly facilitating the removal of said top.

From the foregoing it is thought that the construction and manner of useof my imy proved jar Wrench will be readily under stood.

The device is extremely simple, cheap, durable and may be easily andquickly manipulated in practical use.

It will of course be obvious that my improved Wrench can be made invarious sizes and of other material than that herein set for-th.

The device is also susceptible of many other lminor changes in the formano propor 'tions Without departing Afrom the essential feature orsacrificing any of the advantages of the invention.

Having thus described the invention Wh at is claimed is A jar Wrenchcomprising a jaw member having one of its ends bent at right angles andthe other end curved and attenuated to form a gripping point, and ahandle pivotally connected at one of its ends to the first named end ofthe jaw member and having a lateral extension formed thereon disposed inthe .plane of said handle and on the opposite side of the pivotal1iointthereof, said extension forming a gripping point which is disposedout of alinement with the first mentioned gripping point when the handleand jaw member are disposed in parallel planes, one edge of saidgripping point being convex and adapted to indent the upper edge of acan beneath the cover thereof when pressure is exerted upon the handleto raise the cover.

In testimony whereof I hereunto afix my signature in the presence of twoWitnesses.
